Hi, I've been struggling with FreeBSD's ruby18 port and threads. I realise there's previous discussion[0] about this and I feel I'm blundering somewhat, but here goes.
On both 7.x and 6.x boxes I've built ruby18 with the pthreads knob deliberately turned off (the default). The resultant ruby has problems with deep recursion, shown by this script[1] but less pathologically in production in a busy RoR site too. $ ruby -e 'def d(x); p x; d x+1; end; d 0' This bombs with SIGILL[2]. I note that, as per the conversations linked above, this build uses the GCC option -pthread and links against libthr[3]. If I build the port without -pthread (and related config.h #define), install the library alongside the from-port one, and employ the resultant binary with some libmap.conf guidance I get a ruby which behaves far nicer[4]. I can recurse way deeper and receive a graceful SystemStackError exception when things hit the wall[5]. What's the score here? Clearly there's motive for building like it does, but the hacked ruby works better for me in everyday life. Any ideas? I hope this is on-topic for freebsd-ports. I mailed the maintainer first but got no response. Regards, l.
